Answer:
-16x - 30
Step-by-step explanation:
4(-3x - 5) - (10 + 4x) = 4*(-3x) - 4*5 + (-1)*10 + (-1)*4x
= -12x - 20 - 10 - 4x {add like terms}
= -12x - 4x - 20 - 10
= -16x - 30

<em>4 cups of 75% fruit juice and 4 cups of 25% fruit juice should be mixed.</em>
Step-by-step explanation:
Suppose, the amount of 75% fruit juice is
cups.
As the total amount of fruit punch is 8 cups, so the amount of 25% juice will be:
cups.
Given that, the percentage of juice in 8 cups fruit punch is 50%
So, the equation will be.........

Thus, the amount of 75% fruit juice is 4 cups
and the amount of 25% fruit juice is (8-4)= 4 cups.
Answer:
The computer game would sell for $30.
Step-by-step explanation:
25 (1.20) = 30
3x - 4y = 35
3x + 4y = 5
------------------add
6x = 40
x = 40/6 which reduces to 20/3
3x - 4y = 35
3(20/3) - 4y = 35
20 - 4y = 35
-4y = 35 - 20
-4y = 15
y = -15/4
solution is (20/3, -15/4)
